Improvements for statistics information:

+ Show 2 groups of errors: "Auto-repared" and "Remaning".
 + Use different icons for volumes with/without remaining errors
 + Fixed update of the ObjectList warnings icons after switch the color mode of a PrusaSlicer
 + Some code refactoring: Use same code for tooltips for "exclamation"-icon from an ObjectList and from a Sidebar->ObjectInfo
